Abstract

The mean spherical approximation (MSA) approach for electrolyte solutions is combined with a modified non-random two-liquid (NRTL) approach. The resulting model is suitable for a description of the thermodynamic properties of electrolyte-multisolvent systems. The ability of this MSA-NRTL model is investigated by examining activity and osmotic coefficients of binary and ternary electrolyte solutions. Especially for non-aqueous solutions, the model is superior to standard semi-empirical calculations used in the chemical industry.
